Abby and Brittany Hensel are conjoined twins who share a body. Specifically, they each control half of their body, and learned at a very early age to work together in perfect sync in order to walk and do all the other things people with two arms and legs each do. The Hensel twins had their own reality TV series on TLC a few years ago. What's happened since then? Abby and Brittany graduated from college in 2012 and got a job as math teachers for fourth- and fifth-graders.

While students may think they are going to get two different perspectives, Abby and Brittany are in perfect sync. While they are do not share any brain connections like the Hogan twins, they are very good at completing each other's sentences. They are receiving one salary, with half the funds going to Abby and half to Brittany.
